We would like to be able to calibrate the rRF9E5 ADC
Our proposal is to permanently fit voltage dividers, each using two precision resistors, on two of the ADC Ports and...
At some point in the past I had nrf51+gdb+breakpoints working just fine. I even have a bunch of __BKPT() calls in my various error handlers to trap into the debugger.

Hi,
I'm trying to get S110 softdevice (v8.0.0) working with RIOT. I had some issues (I couldn't initialize TIMER1 or TIMER2 until softdevice is setup & enabled) but I think...
I trying to debug an interaction between using SPIM3 on the nRF52840 and the BLE stack in the SoftDevice . A reset is happening, which I think is being generated by the SoftDevice...
Hi I have an application where ESB will be used in the same environment as a few BLE devices which are also our devices. My plan is to set an rf_channel for ESB and then at...
We have an application where we have a large number of sensors, some relay nodes and one or more gateways. The sensors and relay nodes are provisioned by the gateways and...
Hi, I can normally log with NRF_LOG_INFO(). But if i enable softdevice (bluetooth stack init) logging stops working. Interesting part is that there are several log lines before...
BLE Control by Main CPU (MCU):
1. How the MCU communicates with BLE HW?
2. What is the amount of MCU performance is required to control the BLE? (expected answer example...
Hi nordic.
I use SDK 14.20 and nrf52840 board and s332 softdevice.
Our app has to use ant+ and ble.
My device connect with app.
App requests device to ant+ scanning...
